Producing Method of Continuous Cylindrical Extruding Net and Equipment Thereof

Abstract

A continuous extruding method of an elastomeric cylindrical mesh is provided with steps of: providing a thermoplastic elastomeric plastic for melting and mixing; and providing the melted thermoplastic elastomeric plastic from at least two concentric circles in opposite direction to form multiple thermoplastic elastomeric filaments, and the thermoplastic elastomeric filaments are fused at a site where overlapped to form the elastomeric cylindrical mesh. The extruding die head provided by the present invention is capable of continuously producing the mesh structure which could consider the relatively simple and low cost compared with the conventional production method.

What is claimed is: 
     
         1 . A continuous extruding method of an elastomeric cylindrical mesh comprising steps of:
 providing a thermoplastic elastomeric plastic for melting and mixing; and   providing the melted thermoplastic elastomeric plastic from at least two concentric circles in opposite direction to form multiple thermoplastic elastomeric filaments, and the thermoplastic elastomeric filaments are fused at a site where overlapped to form the elastomeric cylindrical mesh.   
     
     
         2 . The method as claimed in  claim 1 , wherein the elastomeric cylindrical mesh is further cooled and set. 
     
     
         3 . The method as claimed in  claim 1 , wherein the elastomeric cylindrical mesh is further applied with an external force for pulling the site where the thermoplastic elastomeric filaments overlapped. 
     
     
         4 . A continuous extruding equipment of an elastomeric cylindrical mesh comprising:
 a mixing screw;   a feeding tube;   an extruding die head;   a cooling unit;   the mixing screw, the feeding tube, the extruding die head, and the cooling unit are set in order and connected by a melted fluid; wherein   the extruding die head comprises an outer output unit and an inner output unit in a concentric setting;   the outer output unit and the inner output unit are rotated in the opposite direction;   the outer output unit and the inner output unit each comprises multiple outer discharging ports and inner discharging ports thereon respectively; and   the outer discharging ports and the inner discharging ports are set in concentric but staggered.   
     
     
         5 . The equipment as claimed in  claim 4 , wherein the inner discharging ports are set in an angle towards the outer discharging ports. 
     
     
         6 . The equipment as claimed in  claim 4 , wherein a middle output unit comprising multiple middle discharging ports is further set between the outer output unit and the inner output unit via spacers.
